Abstract: THE DISCLOSURE PERTAINS TO A NEW COMPOSITION OF MATERIALS IN THE FORM A POROUS CEMENTED COMPOSITE AND A METHOD OF MAKING THE SAME. METAL POWDER SUCH AS COPPER IS MIXED WITH A CEMENT BINDER SUCH AS PORTLAND CEMENT. WHEN PREPARED AS A SLIP, POURED AND CURED, THE CEMENTED METAL POWDER HAS SUFFICIENT GREEN STRENGTH TO HOLD TIS SHAPE MAKING IT SUITABLE FOR CASTING PURPOSES. BY TREATING THE GREEN COMPOSITE WITH A HEADENING AGENT, SUCH AS AMMONIUM HYDROXIDE, IT IS HARDENED AND STRENGTHENED SO AS TO WITHSTAND GRIDING, POLISHING, MACHINING OR OTHER OPERATIONS NORMALLY ASSOCIATED ONLY WITH WORKING ON SOLID METALS. A METAL FIBER MAY BE MIXED WITH OR SUBSTITUTED FOR THE METAL POWDER WITH GOOD RESULTS.
